A high-capacity quick charge battery "Pronto" review that will fill up 13500 mAh in just one hour

The battery becomes empty in 1 or 2 days Although it is a large-capacity mobile battery that is useful when carrying a smartphone or tablet, as the battery capacity increases, the charging time becomes longer, once forgetting to charge There are many people who have experienced smartphones and mobile batteries are out of truth and disastrous ...... The problem of such a mobile battery is solved with its own rapid charging system, the capacity of 13,500 mAh can be charged to full with 1 hour, and fast charge battery which can store power for one smartphone even by charging only 5 minutes "Pronto"is. In 2014 Kickstarter was looking for investment and commercialized it and got it to the editorial department of GIGAZINE, so I tried to verify whether it is really possible to charge quickly.

◆ opening & photo review
So, "Pronto 12" with capacity of 13500 mAh and "Pronto 5" with capacity of 4500 mAh arrived.


The lid on the front opens so that the mobile battery is contained in each.


There is also a brief explanation, Pronto 12 charges one smartphone by charging for 5 minutes · It can store electric power that can charge up to 1.25 action cameras and tablets to 1 / 4th, if you charge for 1 hour It will be full. If it is in a fully charged state, it means that you can charge a notebook PC for seven smartphones, nine action cameras, two tablets, and one notebook.


Pronto 5 can charge up to 15 smartphones with 15 minutes of charge, up to 1.5 action cameras and 1 tablet quarter. The time it takes for the battery to fill up is the same as Pronto 12 in one hour. If it is fully charged, it means that you can charge up to 3 smartphones, an action camera of 4.5, and a tablet up to 3/4.


Looking out from the box looks like this. Pronto 12 on the left and Pronto 5 on the right, respectively, the type of charger is different, Pronto 12's charger has an AC adapter with a converter like a laptop PC and a cigar socket for connecting to a cigar lighter type AC inverter A type adapter is attached.


I tried arranging two batteries. Both are larger sizes as mobile batteries.


Weight of Pronto 12 is 494 g in actual size


The weight of Pronto 5 was 234 g in actual size


When viewed from the top, they are as big as the iPhone 6 Plus


From the side, you can see that the width of Pronto 12 is about twice as thick as Pronto 5.


Try bringing the larger Pronto 12 in your hand like this. It may be useless since it is a large capacity battery of 13500 mAh, but it also has weights heavily, it's a bit inconvenient to carry around. In the explanation of Kickstarter, it was said that it was possible to wear a carabiner, but it seemed to be changed to a cloth band. Since the cloth band is easy to come off, it seems to be difficult for you to "carry the backpack with gashigashi."


The yellow part is designed to let the lid off, and when you remove the lid, two USB output ports of 2.4 A are on the left side, charging start button in the middle, 12 V socket (12 V OUT) outputting to the AC inverter on the right and charging There is a socket (INPUT) to insert the instrument.


Voltage at battery charging is 12 V / 5 A, and at output 5 V / 2.4 A. Also, if it is a cigar socket type adapter, it is possible to output at 12 V, so you can charge PC etc as well.


Two LED indicators are pushed on the surface, you can check the output level when charging with the one on the left side when the side with the yellow lid is facing up, and the remaining battery capacity on the right side.


If you put the smaller Pronto 5 in your hand


From the left is a socket for charger and Mini-USB power supply port, charging start button, 3A USB output port is one.


When you actually charge it, the LED indicator lights up as follows. At a glance, you can see "whether you can charge quickly" and "how much capacity can be stored".


Can you quickly charge the power for one smartphone in 5 minutes really?
That's why I really want to charge the Pronto 12 for 5 minutes to verify if you can store the power for one smartphone. First of all, I completely discharged the battery and made a state where it does not react at all even if I push the start button.


Charging starts with a dedicated charger. The LED on the left shows the charge level at Max and you can see that it is being charged quickly.


In the picture I got 10 seconds gap, but stopped power supply in 5 minutes. Looking at the LED on the right side, you can see that only one sixth of the total amount of electricity can be stored because only one lamp is lit.


So, with Pronto 12 charged only for 5 minutes, you can see how much charge you can charge from charging the iPhone 5 that has discharged to 0% of the remaining battery level, from the following movie.

Connect the iPhone 5 with the battery empty to the Pronto 12 and start charging by pressing the start button. According to the manual "It is written that one smartphone" varies depending on the battery capacity of the smartphone, but Kickstarter explained that "iPhone 5 is one car", so iPhone with a battery capacity of 1440 mAh I decided to verify with 5. IPhone 5 is set to in-flight mode before discharging and it is set not to use the battery as much as possible by Wi-Fi or net communication.


When charging for about 1 hour, the LED of Pront 12 no longer lights up, it seems that the electricity stored for 5 minutes is gone. When I looked at the battery level of iPhone 5, I was able to charge up to "69%", but it did not reach until it was full.


However, trying to do the same verification on another day, I charged the Pronto 12 for about 7 minutes instead of 5 minutes, I tried charging the empty iPhone 5 as it is, up to 79% at that time I was able to charge it. "If it is five minutes in one smartphone" it seems that it can not be filled up with a battery of 1000 mAh or so, but if you charge for 10 minutes, you can fill it up with iPhone 5, so you can lie to the function of "quick charge" I found that there was no.


◆ Can you quickly charge a large capacity battery of 13500 mAh normally taking half an hour in one hour?
Also, although Pronto 5 and Pronto 12 have different battery capacities, they can charge quickly in 1 hour, so you can see the movies you actually charged for 1 hour from the following.

Charged 13500 mAh with quick charge battery 'Pronto' in 1 hour - YouTube


Charging starts by inserting a dedicated charger for each. Pronto 5 can also be powered from USB, but it can not be quickly charged with USB, so be careful.


After 1 hour, both of the LED indicators of the two batteries showed full, and it turned out that it was able to store the capacity of 4500 mAh and 13500 mAh mobile batteries in one hour really.


Also, when I tried using Pronto 12 for a while while using it, I took up space in my bag, and I was concerned about the weight, but even if I charged the iPhone 5s + Xperia Z3, the rest of Pronto 12 in one day The quantity never goes out. Even just charging Pronto for a few minutes before going out can store enough electric power, I was able to use mobile terminals with confidence.

There was one editing member using a mobile battery with a capacity of 15000 mAh, but it took about 6 hours to fully charge, so Pronto 12, which can store 13500 mAh in 1 hour, It is a quick-charge battery that is handy for people who carry a terminal. The Pronto series batteries can be purchased from below, and the price is $ 79.99 for Pronto 5 (about 9000 yen) and Pronto 12 for $ 149.99 (about 17,000 yen).
